OPENGL源程序，比较不错的。让大家共享一下

主要用于C++调用Opengl时的碰撞检测，内容很好，稍加修改便可以制作自己的虚拟场景-Mainly used for C++ Call opengl at the time of collision detection, content very good, a little modification will be able to create their own virtual scene

创建OpenGL窗口的基本代码，自己觉得很有用，与大家分享。-Create OpenGL window for the basic code, feel useful, to share with you.

一个基于opengl的cad应用的好例子，可以学习如何将mfc 与opengl结合使用，需要opengl扩展库-a cad on opengl application of a good example, can learn how to mfc opengl combined with the need for expansion opengl

“虚拟地景生成系统”是基于Windows2000系统和Visual C++ 6.0平台，利用基本OpenGL函数编程技术开发的三维可视化成果。它通过简单的DEM（数字高程模型）数据，建立格网模型、再根据光照强度、高程值及有关数据建立数学模型，生成晕渲，再将它投影到平面上，达到模拟现实地貌起伏的效果。 本系统采用XP风格界面，清新自然。它具有透射/正射投影切换、漫游、缩放功能。支持分层晕渲、比高设定、平移、旋转、翻滚、视野调节、雾化、纹理贴图(显示/隐藏)等诸多功能，单幅、1MB大小的DEM数据生成速度为秒级，浏览时无停顿。-"to the virtual scene generation system" is based on Windows 2000 and Visual C 6.0 platform, using the basic function of OpenGL programming technology developed by 3D visualization results. Through simple DEM (Digital Elevation Model) data, establish grid model, in accordance with light intensity, elevation data and the value of a mathematical model, generate Hillshading, then it projection plane to achieve realistic simulation of the effect of undulating topography. The system uses XP style interface as well. It has transmission/switching are overhead projectors, roaming, zoom function. Support for layered Hillshading, compete against the creation, translation, rotation, rolling and vision adjustment, atomization,

本程序主要通过不断改变视口位置来模仿动画效果，同时介绍了在进行opengl绘图时所做的一些不可或缺的准备工作-This procedure primarily by changing location, as I imitate animation effects, while the introduction during the opengl drawing done some essential preparatory work

opengl实现的一个太阳系系统，可以通过界面来控制各个星球运转的速度。交互性比较好。-opengl achieved a solar system, can interface to control the operation of all the speed planet. Interactive is good.
